Femtosecond laser versus mechanical microkeratome laser in situ keratomileusis for myopia: Metaanalysis of randomized controlled trials.

2011

Purpose To examine differences in efficacy, accuracy, safety, and changes in aberrations between femtosecond and mechanical microkeratome laser in situ keratomileusis (LASIK) for myopia. Setting Department of Ophthalmology, Shanghai First People's Hospital Affiliated to Shanghai Jiaotong University, Shanghai, China. Design Evidence-based manuscript. Methods Data sources, including PubMed, Medline, EMBASE, and Cochrane Controlled Trials Register, were searched to identify potentially relevant prospective randomized controlled trials. Primary outcome measures were efficacy (uncorrected distance visual acuity ≥20/20), accuracy (±0.50 diopter mean spherical equivalent), and safety (loss of ≥2 l…

Smart and resilient manufacturing in the wake of COVID-19.

2021

Since 2020, manufacturers have been facing unprecedented and extraordinary challenges with the COVID-19 outbreak, which severely disrupted manufacturing operations around the world. Some manufac- turers have shifted gears to help address dire shortages during the coronavirus pandemic. Others were thrown into deep unknowns and faced with the grim prospect of being closed down. We have seen a sprawling network of multinationals and local businesses step in to fill a void by using 3D printers to make personal protective equipment (PPE) such as face shields, respirator masks, nasal swabs and even ventilator parts. Large manufacturers attempted to rejig parts of their production lines to mass-pr…
